Ice-cream maker

Abstract

An ice-cream maker comprises: a material vessel into which ice cream materials are to be put; a stirring blade for stirring the materials received in said material vessel; a motor connecting to said stirring blade; a temperature sensor making contact with said material vessel; a cooking chamber into which said material vessel is attached so as to come into close contact with said cooking chamber; a freezing cycle for freezing said material vessel; and a heater for heating said material vessel.

We claim: 
     
       1. An ice-cream maker comprising: a material vessel into which ice cream materials are to be put;   a stirring blade for stirring the materials received in said material vessel;   a drive for driving said stirring blade;   a temperature detector for detecting a temperature of said material vessel;   a cooking chamber into which said material vessel is inserted so as to come into close contact with said cooking chamber;   a freezer for freezing the material vessel;   a heater for heating said material vessel;   a controller for carrying out: a heating/stirring process including stirring the materials while heating said material vessel up to a bactericidal temperature by driving said heater and said drive;   a cooling process of cooling the materials by continuously driving said drive after stopping said heater; and   a freezing process of freezing the materials to a freezing temperature by driving said freezer;     a storing device for storing a plurality of interface display menus;   a selector for selecting a desired interface display menu from said storage device; and   a notifier for notifying said controller of termination of each process.   
     
     
       2. The ice-cream maker according to claim 1, wherein said material vessel includes a heating vessel and a cooling vessel, wherein a bottom portion of said heating vessel makes contact with said heater and a bottom portion of said cooling vessel is positioned distant from said heater. 
     
     
       3. The ice-cream maker according to claim 1, wherein said interface display menus stored in said storage device include: an interface display menu for instructing said processor to carry out the heating/stirring process, the cooling process and the freezing process continuously;   an interface display menu for instructing said processor to carry out the heating/stirring process and the cooling process; and   an interface display menu for instructing said processor to carry out only freezing process.   
     
     
       4. An ice-cream maker comprising: a material vessel into which ice cream materials are to be put;   a stirring blade for stirring the materials received in said material vessel;   a drive for driving said stirring blade;   a temperature detector for detecting a temperature of said material vessel;   a cooking chamber into which said material vessel is inserted;   a freezer for freezing said material vessel;   a heater for heating said material vessel;   a cooler for cooling the materials heated by said heater, to a predetermined temperature;   a controller for carrying out: a heating/stirring process including stirring the materials while heating said material vessel up to a bactericidal temperature by driving said heater and said drive;   a cooling process of cooling the materials by driving said cooler after stopping the heater while continuously driving said drive; and   a freezing process of freezing the materials down to a freezing temperature by driving said freezer;     a storing device for storing a plurality of interface display menus;   a selector for selecting a desired interface display menu from said storage device; and   a notifier for notifying said controller of termination of each process.   
     
     
       5. The ice-cream maker according to claim 4, wherein said interface display menus stored in said storage device include: an interface display menu for instructing said processor to carry out the heating/stirring process, the cooling process and the freezing process continuously;   an interface display menu for instructing said processor to carry out the heating/stirring process and the cooling process; and   an interface display menu for instructing said processor to carry out only the freezing process.   
     
     
       6. The ice-cream maker according to claim 4, wherein said material vessel includes a heating vessel and a cooling vessel, wherein a bottom portion of said heating vessel makes contact with said heater and a bottom portion of said cooling vessel is positioned distant from said heater. 
     
     
       7. An ice-cream maker comprising: a material vessel into which ice cream materials are to be put;   a stirring blade for stirring the materials received in said material vessel;   a motor connecting to said stirring blade;   a temperature sensor making contact with said material vessel;   a cooking chamber into which said material vessel is inserted so as to come into close contact with said cooking chamber;   a freezing cycle for freezing said material vessel; and   a heater for heating said material vessel;   wherein said material vessel includes a heating vessel and a cooling vessel, wherein a bottom portion of said heating vessel makes contact with said heater and a bottom portion of said cooling vessel is positioned distant from said heater.
